Geometry na Mota - Dabarun

Geometry na dabara yana ɗaya daga cikin mahimman sigogin da ke shafar tuki, lalacewa tayoyin mota, jin daɗin tuƙi da amfani da mai. Daidaitaccen saitin sa zai yi tasiri sosai akan aikin tuƙi na abin hawa, da yadda ake sarrafa ta. Babban abin da ake buƙata shi ne ƙafafun su yi birgima, amma kar su zamewa yayin da ake yin kusurwa ko a madaidaiciyar layi. Dole ne a saita ma'auni daidai gwargwado akan dukkan ƙafafun abin hawa, ba kawai gatari mai tuƙi ba.

Ikon sarrafa abin hawa shine ikon yin tafiya cikin aminci da sauri da sauri a kewaya tare da yanayin da aka bayar. Ana iya sarrafa canjin alkiblar mota ta hanyar juya ƙafafun. Ƙaƙƙarfan motocin ababen hawa bai kamata su zame ba yayin da ake yin kusurwa, amma ya kamata su mirgina don canja wuri gwargwadon iko da kewaye gwargwadon yiwuwa. Don cika wannan yanayin, karkacewar dabaran daga hanya dole ne ya zama daidai da sifili. Wannan shine Ackerman steering geometry. Wannan yana nufin cewa tsayin gatura na jujjuyawar dukkan ƙafafun suna tsaka-tsaki a wuri ɗaya kwance akan axis na kafaffen gatari na baya. Wannan kuma yana ba da radius na juyawa na kowane ƙafafun. A aikace, wannan yana nufin cewa tare da axle mai tuƙi, lokacin da aka juya ƙafafun a kan hanyar da ake so, akwai wani kusurwa na daban na ƙafafun saboda hanyoyin da ba daidai ba. Yayin aiki, ƙafafun suna birgima a kan madauwari waƙoƙi. Dole ne kusurwar jujjuyawar dabaran jagorar ciki ta zama mafi girma fiye da kusurwar juyawa na waje. Geometry na haɗin gwiwar gama gari yana da mahimmanci a cikin ƙayyadaddun ƙayyadaddun ƙayyadaddun bambance-bambancen, bambanci a cikin kusurwoyi na canji a cikin yatsan ƙafar ƙafafu. Dole ne wannan kusurwar bambanci ta kasance iri ɗaya a cikin duka wuraren tuƙi lokacin da ƙafafun ke juyawa a cikin hanya, watau lokacin juya dama da hagu.

Daidaitaccen lissafin lissafin geometry: cotg β₁  - gaba β₂ = B/L, inda B shine tazara tsakanin gatari na tsaye na hinges, L shine wheelbase.

Abubuwa na geometric suna shafar kulawar abin hawa lafiya, halayen tuƙinsa, lalacewar taya, amfani da mai, dakatarwa da haɗe -haɗe na ƙafa, kayan tuƙi da suturar inji. Tare da zaɓin sigogi masu dacewa, an sami jihar da matuƙin jirgin ya tabbata, ƙarfin tuƙin da ke aiki akan matuƙin jirgi ƙarami ne, suturar duk abubuwan da aka gyara kaɗan ne, nauyin axle ba shi da faɗi, kuma an ƙaddara wasan tuƙi. Zane mai ɗaukar gatari ya haɗa da abubuwa da yawa waɗanda ke haɓaka haɓakar chassis da haɓaka ta'aziyar tuƙi da ingantacciyar ƙwarewar tuƙi. Ainihin, wannan shine ƙaurawar gadar gadar, haɗuwa da gatari na baya, bututun tashi, da sauransu.

Geometry matuƙin jirgi yana da tasiri ƙwarai da halaye na keɓaɓɓen abin hawa, halayen dakatarwa da kaddarorin tayoyin, waɗanda ke haifar da haɗin gwiwa tsakanin abin hawa da hanya. Motoci da yawa a yau sun tsara saitunan geometry na baya, amma har ga motocin da ba za a iya daidaita su ba, daidaita geometry na duk ƙafafun huɗu zai ba ƙwararren masanin damar gano duk wata matsalar waƙa ta baya kuma gyara su ta hanyar daidaita gatarin gaba. Daidaitawar ƙafa biyu, wanda kawai ke daidaita geometry na ƙafafun gaba dangane da gindin abin hawa, ya tsufa kuma ba a amfani da shi.

Alamomi na geometry mara inganci

Kuskuren da ba daidai ba na geometry na ƙafa yana haifar da lalacewar yanayin fasaha na motar kuma yana bayyana ta alamun da ke gaba:

• taya sanye
• matalauta iko Properties
• rashin kwanciyar hankali na sarrafa motsin motsi
• rawar jiki na sassan kayan sarrafawa
• ƙara lalacewa na sassan tuƙi na mutum da karkacewar tuƙi
• rashin iya dawo da ƙafafun a gaba

Mafi kyawun jeri na dabaran mota shine daidaita dukkan ƙafafu huɗu. Tare da wannan nau'in saitin lissafi, mai fasaha yana shigar da na'ura mai nuni akan dukkan ƙafafu huɗu kuma yana auna ma'auni akan dukkan ƙafafun huɗu.
